Joerg,

Can this patch please be dropped or reverted? It's still breaking
tegra_defconfig in next-20120517 since the dependencies I mentioned
above aren't satisfied. At this stage, it seems unlikely that the DMA
window parsing change is going to make it into 3.5, so this isn't just a
temporary issue.

Thanks.
